Undercore is a genre of music that is either a remix of or made in a similar style to the soundtrack of the undertale OST by Toby Fox. Prominent Undercore artists include SharaX, Ethan Harper, and Keno9988iiii. Most Undercore music in a more “pure” style usually lifts the sound fonts/samples in their work directly from Undertale and Fox’s work themselves, with little other instruments being used; whereas most Undercore music in a more remix type still typically just lifts the leitmotifs from the game and uses completely new instruments, still keeping the Undertale feel, but not the exact musical style of Fox’s works.
